What They Have in Common
Both are carry bags listed around $290. Neither is sold as waterproof, and Sun Mountain doesn't say whether a rain hood is included — Stitch confirms there isn't one. Neither publishes full-length divider details or a cooler pocket.
Where They Differ
Weight and Carrying Setup
The Stitch weighs 4.56 lbs — worth noting that Stitch publishes this as 73 oz including the strap, and that's our conversion. The Sun Mountain lists at 4.8 lbs. A quarter pound doesn't sound like anything in the parking lot. After 14 holes in July, you'll know exactly where it went.
More importantly: the Stitch has a double strap, the Sun Mountain has a single. A single strap over 18 holes means you're shifting the bag from one shoulder to the other every few holes, or you're walking lopsided. A double strap distributes the load across your back. For a bag you're actually carrying — not just Sunday-parring it around nine holes — that distinction matters more than the weight gap.
Club Organization
The Stitch has a 4-way top on an 8 × 10 inch opening; Sun Mountain specs a 3-way on a 5.25-inch top. Stitch says it fits 14 clubs. Sun Mountain doesn't state a club capacity for the Swift Sunday, and with fewer dividers you'll have more shafts sharing space — more tangling, more digging around to find the right club. A 14-way isn't necessary for a carry bag, but the step down from 4 to 3 is real.
Pockets and Storage
Sun Mountain publishes six pockets, including two velour-lined valuables pockets and a zip-off ball pocket. Stitch doesn't publish a pocket count, but it names a magnetic ball pocket with a felt-lined valuables pocket, an apparel pocket, a pencil pocket, and stretch-pocket construction.
If you need to count pockets before you buy, the Sun Mountain is the one that gives you the answer. If the storage sounds like enough from the Stitch's description, the pocket count gap probably won't change your round.
Material and Weather
The Stitch is water and stain resistant nylon with YKK zippers. Sun Mountain publishes no material. Neither bag is sold as waterproof. The Stitch is explicit about that — water and stain resistant, not waterproof. Sun Mountain's page doesn't make a waterproof claim either way, and doesn't say whether a rain hood is included.
Who Should Buy Which
Get the Stitch SL2 Air Walker if:
- You're walking 18 and your back notices after hole 12
- You want a double strap without upsizing to a full stand bag
- The rain hood absence is fine because you have one already or you're in a dry climate
- A 4-way top and a magnetic ball pocket cover your storage needs
Get the Sun Mountain Matchplay Swift Sunday if:
- You're playing shorter rounds — nine holes, a par-3 course — where a single strap is less of an issue
- The zip-off ball pocket or six-pocket layout genuinely fits how you organize your gear
The Bottom Line
The Stitch SL2 Air Walker has the double strap, and that's the argument. For a carry bag, how the weight sits on your body over a full round is the whole game, and a double strap wins that comparison by default. The Sun Mountain has more pockets — or at least tells you so — and the zip-off ball pocket is a nice touch. But it's heavier and single-strapped, which is a tough combination for anything past a few holes. The $8 list price gap doesn't move the needle.
